Abstract

A turbine wheel for a turbine charger includes a hub and a set of wheel blades configured to be arranged around the hub. A wheel blade has a section structure of an air-foil which has a pressure side and a suction side. The turbine wheel is capable of remarkably increasing an output of a vehicle engine by increasing a rotation power of the turbine wheel to increase a compression rate of sucked air.

First claim

What is claimed is:

1 . A turbine wheel for a turbo charger, comprising:
a hub; and a plurality of wheel blades configured to be arranged around the hub, wherein a wheel blade among the plurality of wheel blades has a section structure of an air-foil which has a pressure side and a suction side.

2 . The turbine wheel according to claim 1 , wherein the section structure of the air-foil is formed along an inflowing direction of exhaust gas.

3 . The turbine wheel according to claim 1 , wherein the wheel blade has a take-out tip through which exhaust gas is discharged.

4 . The turbine wheel according to claim 3 , wherein the take-out tip of the wheel blade has a take-out angle of 0 to 15 degrees.

5 . The turbine wheel according to claim 3 , wherein the take-out tip of the wheel blade has a take-out angle of 30 degrees.

6 . The turbine wheel according to claim 1 , wherein the wheel blade is provided with an air inflow passage through which air is introduced.

7 . A turbine wheel for a turbo charger, comprising:
a hub; and a plurality of wheel blades configured to extend from the hub in an outer diameter direction, wherein a wheel blade among the plurality of wheel blades has a section structure of an air-foil which is formed along an inflowing direction of exhaust gas and has a pressure side and a suction side, and the wheel blade is configured to make the inflowing direction of the exhaust gas and a discharge direction of the exhaust gas orthogonal to each other.

8 . The turbine wheel according to claim 7 , wherein the wheel blade has a free end provided with a take-out tip through which exhaust gas is discharged.

9 . The turbine wheel according to claim 7 , wherein the wheel blade is provided with an air inflow passage through which air is introduced.
